Be it known that 1, CHARLES F. SNIDER, a

citizen of the United States, residing at Mount ing Device, of which thefollowing is a specification.

This invention relates to binding devices for loose leaves of anycharacter, and more especially to that class of binding devices whichprovide for binding in package or book form loose leaves or sheets.

To this end the invention primarily contemplates an improved binderhaving means for conveniently binding together bank-deposit tickets orslips, sales tickets, loose notes, vouchers, or, in fact, any papersthat are usually kept on file and put away for future reference.

In its special application the invention is designed, primarily, as abinder for bank-deposit tickets to provide for binding the latter inpackages of any desired size in the form of a book, so that While beingheld together compactly and within a small compass an individual ticketor slip can be conveniently referred to without unlocking the binder orotherwise disturbing the package. In this application of the inventionthe same is designed for use in connection with any filing deviceembodying a punch for cutting holes.

in the tickets or slips and filing them from day to day on spindles,with date-slips for each day.

A further object of the invention is to pro vide a binder constructed ina simple and practical manner and adjustable to any thickness or size ofpackage to be bound, besides being held in a locked condition by theexpansive pressure of the package confined between the clamp members ofthe device.

With these and other objects in view, which will more readily appear asthe nature of the invention is better understood, the same consists inthe novel construction, combination, and arrangement of partshereinafter more fully described, illustrated, and claimed.

The essential features of the invention for effecting the object soughtfor are necessarily susceptible to some modification; but the preferredembodiments of the improvements are shown in the accompanying drawings,in which Figure 1 is a perspective view of a temporary binder shownapplied to abunch orpackage of bank-deposit tickets with date slips orcards interposed therebetween; Fig. 2 is a cross sectional view of thebinder, showing the interlocked position of the clamp members. Fig. 3 isa perspective view of the binder with the clamp members in the positionthey occupy when about to be assembled upon a bunch or package ofleaves. Figs. 4 and 5 are details in perspective, respectively of theseparate clamp members andthe binder.

Like numerals of reference designate corresponding parts in the severalfigures of the drawings.

he device as an entirety is in the form of an extensible clamp carryingfile-spindles upon Which are strung the leaves or sheets to be boundtogether and having means for being tightly clamped upon the package ofleaves or sheet-s at one end or edge thereof, so as to provideaholding-back therefor and permitting of free reference to anyindividual leaf or sheet held thereby. The said extensible clampcomprises a pair of separable interlocking members 1 and 2, which areduplicates in general shape and size and of an approximate L shape incross-section, said clamp members being designed to loosely register onewithin the other.

Each of the clamp members 1 and 2 consists of a flat back-piece 3,preferably of a rectangular shape and provided at one edge with anofiset right-angularly-disposed clip flange or plate 4, whichconstitutes the clamp portion of the member and clips upon the edges ofthe leaves, sheets, cards, or other slips to be bound together. One ofthe clamp members (designated by the numeral 1) is provided in the flatback-piece 3 thereof with a keeper 5, preferably in the form of a slotor opening located contiguous to the edge of the back-piece 3, oppositethe flange 4:, and provided with a beveled edge 6 tofacilitate theinterlocking engagement of the keeper with the series of catch-tongues'7, provided upon the back-piece of the other clamp memher 2, The saidcatch-tongues 7 of the clamp member 2 are transversely alined at a pointintermediate the end edges of the back-piece of said member 2, and theseries of said tongues extend entirely across the back-piece of themember carrying the same to provide means for interlocking the twomembers of the clamp in any extended or contracted position. The saidcatch-tongues 7 are preferably struck out from the back-piece of theclamp member 2 and project at the same inclination and in the samedirection from the inner side of the said-baek-pieee, and the tongues 7are of a sufficient resiliency to freely ride upon the beveled side ofthe keeper slot or opening 5 as the two clamp members are compressedtogether upon the package of leaves or sheets to be bound therebetween.

To provide for the proper retention of the leaves or sheets within theextensible clamp, the clamp member 1 has projected from the inner sideof its clip-flange t one or more filesleeves 8, disposed in parallelismwith the back-piece of the clamp-section 1 and designed to telescopeupon the complementary pins 9, projected from one side of the clipfiangei of the member 2 and arranged in parallelism to the back-piece of saidmember, and it will be observed that the registering sleeves and pins 9constitute telescopic filespi'ndles for holding the leaves or sheets ina properly-alined condition within the clamp members of the binder.

In using the binder after stringing the leaves, sheets, or other matterupon the filesleeves 8 of one of the clamp members the pins 9, carriedby the other member, are inserted into the open ends of the said sleeves8,and the two clamp members are then pressed upon the edge of thepackage therein. After tightly forcing the clip flanges of the two clampmembers upon the package the pressure of the hand is released from thedevice, whereupon one of the catch-tongues 7 of the clamp member 2 willbe thrust by the expansive force of the package into tight interlockin gengagement with the keeper 5 of the clamp member 1, thus securelylocking the binder upon its package and preventing the accidentalloosening thereof. l/Vhenever it is desired to unlock the binder, so asto remove a leaf or sheet or to place others into position, it is simplynecessary by means of a key or other flat instrument inserted betweenthe overlapping back-pieces of the two sections to disengage the activecatch-tongue from the keeper or slot and then draw the two clamp membersapart Of course prior to this op eration it is necessary to press theclamp members upon the package to carry the active tongue out of itslocking-plane.

In the ordinary use of the'device as a binder for bank-deposit ticketsor the like, in connection with which a two-spindle ticket-file is used,as in some constructions now on the market, the sleeve-sections 8 of thehereindescribed binding deviccarc slipped over the pointed ends of thespindles of the file on which the tickets are filed and the ticketsslipped onto the said sleeve-sections 8 of the binder. Then the pointsof the file-pins 9 of the binder are inserted into the sleeves 8, onwhich the tickets are strung, and the clamp members of the devicepressed together in the manner described, with the parts having such aposition that the back-piece of the clamp member carrying thecatch-tongues 7 will pass down on the outside of the backpiece of theother member and ride over the keeper-slot 5 until the pressure of thehand is released to permit one of the catch-tongues to be thrown intoengagement with the keeper slot or opening by the expansive force of thetightly-compressed tickets in the manner already explained.

From the foregoing it is thought that the construction, use, and manyadvantages of the herein-described binder will be readily apparent tothose familiar with the art without further description, and it will beunderstood that various changes in the form, proportion, and minordetails of construction may be resorted to without departing from theprinciple or sacrificing any of the advantages of this invention.

Having thus described the invention, what is claimed as new, and desiredto be secured by Letters Patent, is
